AUTOMATIC CUT-OUT AND LlGHTNlNG-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 339,363, dated April 6, 1886.

Application filed September 12, 1885. Serial No. 176,914. (No model.)

To aZZ whom it may concern:

Be it known that I, PERLEY Pooa BELT, of Columbus, in the county of Cherokee and State of Kansas, have invented a new and Improved Automatic Out-Out and Li ghtning- Arrester, of which the following is a full, clear, and exact description.

My invention relates to cut-outs and lightning-arrcsters for use in telegraph, telephone, or other stations where electrical line-instruments are used; and it consists of the construction and arrangement of parts as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a plan view of my complete apparatus, showing the same in connection with the station-instruments; and Fig. 2 is a side view of the device.

In the drawings referred to I have shown my apparatus as being mounted upon a block or stand, A, to the center of which there is secured a smaller block, A, both of said blocks being made of some insulating material.

B B are two electro-magnets wound with coarse heavy wire and supported by metallic springarms b b, which are secured to and project outward from the block A, said electro-niagnets being so arrangedthat their polepieces 0 0' closely approach but do not come in contact with each other. The arms b 1) project beyond the magnets 13 B, and at their ends carry contact-points a a, which project inward toward a central standard, (I, to which there are secured the contacts e 6 in line and arranged to co-operate with the contacts a a. The standard d is in electric connection with the earth, being connected with the bindingpost 0, from which the ground-wire leads, by means of a metallic strip or wire, f, and screw, as g, or by any other convenient form of connection. The line-wire leads to the bindingpost D, thence to the arm b,which is in electric connection with the coil of the electromagnet B,through the coil and on to the bind ing-post E, thence to the line-instruments lo cated at the station, back to the binding-post E, through the coils of the magnet B and. the arm 2/ to the post F and on to the line.

As before stated,the coils of the magnets 13 B are made of heavy coarse wire, so that the ordinary working-current will not produce any appreciable effect upon the apparatus; but when the line becomes abnormally and heavily charged--as before or during an electric storm-the increased current will act to thoroughly charge the magnets, and the at traction exerted by each upon the other will cause them to approach until. theircontact points a a are brought into electric connec tion with the contacts 0 0, thereby grounding the line.

Such an apparatus as I have described is simple in construction and eifective in operation, and will not interfere with the ordinary working of the line.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with two magnets lo cated in a main circuit, movable toward each other, and having their poles adjacent, and contact-points connected to and movable with said magnets and projecting toward each other, of a body in electrical connection with the earth and extending between the said contact-points, whereby when an abnormallystrong current passes over the line the mag nets will be drawn together, thereby bring ing their contact-points against the body in electrical connection with the ground, and the abnormal current allowed to pass off without breaking the line-circuit, substantially as set forth.

In a cut-out and lightning-arrester, the combination, with two coarsely-wound magnets located in a main circuit and mounted on springs with their poles approaching, of a body in electric connection with the earth and provided with contact-points arranged to cooperate with the points carried by the magnets,whereby any abnormally-strong current will actuate the magnets and ground the line, substantially as described.

3. The combination, with two coarselywound electro-magnets, as B B, mounted on spring-arms, as -b b, with their pole-pieces c c approaching, said magnets being provided with contact-points a a, of a standard, as d, in electric connection with the earth and pro vided with two contact-points, as e 6', sub stantiall y as described.

PERTJEY POOR BELT.
